Fulai Liu, Jinkuan Wang, Ruiyan Du, Bin Wang · 2009
A new two-dimensional direction of arrival (2-D DOA) estimation method is proposed, in this paper. The presented method makes using of blind source separation method based on the second-order identification to estimate the array response matrix. Via the rotational invariance techniques, we can estimate the 2-D DOA from the array response matrix estimation. The estimated elevation angles and azimuth angles is automatically determined. Simulation results are presented verifying the efficiency of the proposed method.
